RAILAY-RAIL FASTENER.

@riginal application led .l'uly l5, 1912, Serial No. 709,601.

To all 107mm l may concern Be it known that l, ERNEST J. Pnrrneiniw,citizen of the United States, residing' at lVayside, in the county ofDawes and State of Nebraska, have invented certain n-ew and usefulImprovements in Railway-Rail Fasteners, of which the following is aspecificat-ion.

This is a division of my application filed July 15, 1912, Serial No.709,601.

This invention relates to improvements in railway rail fasteners and hasfor one of its objects to improve the construction and increase theeiiiciency and utility of devices of this character.

Another object of the invention is to provide a simply constructeddevice whereby the rails are secured to the ties without the necessityfor employing clamping bolts or like devices.

Another object of the invention is to provide a simply constructedrailfasteningdevice whereby any slack or looseness which may be producedbetween the tie and the rail may be corrected without detaching theparts.

lith these and other objects in view the invention consistsI in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention, Figure 1 is aplan view of a portion of a rail and a portion of a tie with theimproved fastening means applied. Fig. 2 is a side elevation of theparts shown in Fig. 1 with the rail in transverse section on the line 22 of Fig. 1. Fig. 3 is a longitudinal section on the line 3 3 of Fig. 1.Fig'. l is an end elevation. Fig. 5 is an enlarged perspective view ofone of the rail holding devices.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved tie is constructed preferably tubular and of metal and ofthe usual exterior dimensions corresponding to the ordinary railway tie.

The tie is represented as a whole at 10.

and is formed in theupper face at the points where the rails, indicatedconventionally at 12, are located, of inwardly directed slots 13, theslots opening outwardly through the Specification of Letters Patent.

Divided and this application filed December 2,

Serial No. 734,563.

upper wall of the tie and likewise through the side walls and extendingfor a distance downwardly in the latter with the portions of the slotswhich are located in the side walls of the tie enlarged laterally, asshown at 14. By this means the portions of the slots which are locatedin the side walls of the tie are T-shaped or under cut as shown.

The portions of the slots which are located in the upper walls of thetie slightly converge toward their inner ends, or with the edge farthestfrom the rail inclined. The adjacent edges of each pair of slots arespaced apart a distance slightly less than the width of the flange ofthe rail so that thle rails slightly overhang the slots of each sie e.

Fitting in each of the slots is a key or locking member which is formedwith an intermediate body portion 15 which corresponds substantially inwidth to the portion of the slot which is located in the upper wall ofthe tie and with a lip 16 conforming to and adapted to engage over theouter edge of the flange of the rail and with another overhanging lip 17at the opposite side and bearing over the adjacent upper face of thetie. At its lower end the stock 10 is formed with a T portion 18 to passthrough the 'l' portion 14 of the slot and to bear beneath the lowerface of the upper wall of the tie. By this means the key may be enteredinto the slot and driven home into the inclined portion of the same andthus firmly clamp the rail to the tie. It will thus be noted that thekeys not only irmly clamp the rail to the tie, but likewise enable thetie to be tightened in case it works loose under the impact of therolling stock or from other causes.

By this simple device the necessity for employing clamp bolts or othersimilar fastening devices is obviated, as the rails are firmly clampedin position upon the tie and may be tightened in event of working loose.

The improved tie is simple in construction, inexpensive tomanufacture,and operates eifectually for the purpose as described.

Having thus described the invention, what I claim is:

1. A tubular metallic railway tie having transverse slots in its upperwall opening outwardly and with slots in its side walls communicatingwith the slots of the upper wall, the lower portions of the slots of thesido walls being of greater width than the upper portions and the upperportions of the slots of the side walls corresponding in width to theouter ends of the slots of the upper wall and overhanging the widerlower portions thereof, and clamp devices engaged in said slots andT-shaped at the lower ends to enable them to pass through the widerportions of the slots of the side walls and with rail engaging lips attheir upper ends.

2. A railway tie having transverse slots i in its upper wall at oppositesides thereof and spaced apart a distance slightly less than the widthof a rail flange, the confronting edges of the slots extending inparallel relations and the outer edges of the slots converging from theouter edges of the ties and with slots in the side walls communicat ingwiththe slots of the upper wall, the lower portions of the slots of theside walls being wider than the slots of the upper wall and the upperportions of the slots of the side walls corresponding in width to theslots of the upper wall and overhanging the lower portion, and fasteningdevices each comprising an intermediate stock for engaging respectivelyin the slots of the upper wall and enlarged at the lower ends to passthrough the enlarged lower ends of the side wall slots and to bearbeneath the upper wall at its lower side and enlarged at the upper endsto engage over a rail flange and the upper face of the tie, said stockengaging against the converging edges of the slots of the uppei1 walland adapted to compress the same against a rail flange.

3. A tubular metallic railway7 tie having transverse slots in theopposite sides of its upper wall and opening outwardly and with slots inits side walls communicating with the slots of the upper wall, the slotsin the upper wall being spaced apart at a less distance than the widthof a flange of a railway rail with their contiguous edges extending inparallel relations and the outer edges converging inwardly and the lowerportions of the slots of the side walls of greater width than the upperportions and the upper portions of the slots of the side wallscorresponding in width to the outer ends of the slots of the upper wallsand overhanging the wider lower portions thereof, and clamp devicesengaging in said slots and T-shaped at the lower ends to enable them topass through the wider portion of the slots of the side walls, the upperportions of the clamp devices having a rail engaging lip at one side anda tie engaging lip at the other side.

In testimony whereof I afiix my signature in presence of two witnesses.
